Abstract: A RF-digital hybrid mode power amplifier system for achieving high efficiency and high linearity in wideband communication systems is disclosed. The present invention is based on the method of adaptive digital predistortion to linearize a power amplifier in the RF domain. The power amplifier characteristics such as variation of linearity and asymmetric distortion of the amplifier output signal are monitored by the narrowband feedback path and controlled by the adaptation algorithm in a digital module. Therefore, the present invention could compensate the nonlinearities as well as memory effects of the power amplifier systems and also improve performances, in terms of power added efficiency, adjacent channel leakage ratio and peak-to-average power ratio. The present disclosure enables a power amplifier system to be field reconfigurable and support multi-modulation schemes (modulation agnostic), multi-carriers and multi-channels.

Abstract: Disclosed is a deposition apparatus for an organic light-emitting diode, which is capable of preventing a large piece of glass from sagging due to gravity. The deposition apparatus allows the glass to be adhered to the lower surface of a planar electrostatic chuck from the center portion toward the edge portion thereof in the state in which it is upwardly convexly bent, thereby preventing deformation of a mask caused by the amount of sag of the glass. In addition, the deposition apparatus enables rapid alignment of the glass and the mask because the glass and the mask are adhered to each other via measurement of respective alignment marks provided thereon after the glass is located as close as possible to the mask without coming into contact with the mask.
